Toroidal Transformers | ILP Transformers Unirange

Supplier: Dyne Industries

ILP Transformers offers aleading range of toroidal transformers; the UNIRANGE of transformers has been rationalised to be used on 220 V, 230 V and 240 V 50 and 60 Hz mains supplies up 1000VA

Price Guide (Inc GST): POA

The UNIRANGE maintains the company's reputation for careful selection of ratings widely used in the electronics industry. Each transformer has a single primary winding to meet the needs of 220 - 240 V operation. Two secondary windings chosen in three volt steps, connected in series or parallel give a wide range of output voltage and current options.

The toroidal transformer has the theoretical ideal shape for producing a transformer with the minimum of material. The high efficiency which is obtained with this type of transformer enables it to be conservatively rated without incurring size or weight penalties. There are no loose laminations or air gaps in the toroidal design which, together with the virtual absence of any external field, makes the ILP toroidal transformer particularly suitable for those applications where electrical and mechanical noise must be kept to a minimum. ILP's high quality and competitively priced toroidal transformers are suitable for all types of electronic equipment.

Installation: The mounting kit supplied with each transformer allows easy mounting to a chassis or gear plate by placing the neoprene washers above and below the transformer and bolting the dished washer down firmly (but not over tight) on top. On no account should a continuous conductive path occur (either intentionally or accidentally) from the dished washer around the outside of the transformer to the chassis or gear plate. This will cause a shorted turn and damage the transformer.
